Mister Banjo, aka Kurt Flipots, was hired by the Axis during World War II to be a spy for them. Whenever he had something to report he played his banjo on a popular radio station so that the Japanese forces can decode his secret notes within his music. He later became one of Captain Marvel's earliest foes, however he is only armed with a banjo. He was presumed dead after a fight with Captain Marvel ended with him falling off a boat, however he later turned out to be alive. He later joined the Monster Society of Evil.
